VS 2008 Address An Out Of Bound Index Error?
Dec 21, 2009
I am experiencing a perplexing error ("Index was outside the bounds of array") that did not surface a few days ago WITH THE CODE UNCHANGED.
I was even able to successfully create an executable file a few days ago. It was therefore a shock to be given this error when testing it today.
The snippet is shown below:
Dim GearArray(lines.GetUpperBound(0), 8) As String For x As Integer = 1 To lines.GetUpperBound(0)
Dim parts() As String = lines(x).Split(",")

I have some code and there are 2 errors which I don't understand I have tried all sorts...
1)The type for variable 'Index' will not be inferred because it is bound to a field in an enclosing scope. Either change the name of 'Index', of use the fully qualified name (for example, 'Me.Index' or 'MyBase.Index').
2)Function 'GetNewPhrase' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used.
I can't get it to work..

I am writing a simple Address Book Application using Typed Dataset & Bound Controls. 1<sup>st</sup> Form for Entering Addresses 2<sup>nd</sup> Form for Adding New 'CITY'. To select a city for address I am using a data bound combo box which shows a list of Cities.
While entering with a address if user found the required City Name is not found in the Combo list, he opens a 2<sup>nd</sup> Form to Add a City name to database & returns to Form1.
Here the expected newly added city doesn't appear in the combo list, so I tried to Refill the underlying table with following code

I'm, using a SQL Server table in a DataGridView and I'm having trouble adding records. I'm new to vb.net but used vb6 for a lot of years so the transition is a little difficult. For now I'm just trying to add a record using a button click but the record key which is setup as integer and to automatically increment by 1 shows as -1 after the record is created. While the data does show in the grid it is never actually posted in the table. Once created I want to select the record just entered.
Here's what I have:
' Declare
Private addedRowIndex As Integer
Code:
Dim newMessagesRow As ArcadeDataSet.messagesRow
newMessagesRow = ArcadeDataSet.messages.NewmessagesRow
newMessagesRow.movie_title = "Added Programmatically"

i have an array of 30 strings , the names of the commands send to the serial port, the serial port adresses 16 devices. each device has its own set of commands.
of course i could make subarrays for each device, but for the saving of memory it would be better to use a integer index to name the commands, so like command 0 to 30.
dim command(29) as array of strings.
dim device(7) as array of devices.

I have a datagridview, with 3 columns, each containing dropdown filters (in the column header). Of the 3 columns, 2 are working perfectly fine, but whenever I try to filter the 3rd column, it gives me this error: (Also all of the column's have the ColumnType property set to: DataGridViewAutoFilterTextBoxColumn) "Index was out of range. Must be non-negative and less than size of the collection. Parameter name: index." The error points to the part that begins with "If dgv1.Rows(e.RowIndex)..."

I just recently started getting an index out of bounds error on one of my arrays at runtime. I was not having this issue previously. It only seems to happen when several items are added to a listbox.
Here is my declaration and code.
Dim ClientActiveMedProbs(frmmain.lstActiveMedProbs.Items.Count) As String
'store all active medical problem information in an array & build a string
For i As Integer = 0 To frmmain.lstActiveMedProbs.Items.Count - 1
ClientActiveMedProbs(i) = frmmain.lstActiveMedProbs.Items.Item(i).ToString
[Code] .....
The actual error message is:
Index was outside the bounds of the array.

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

I have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?

I don't normally use strongly typed datasets, but I am maintaining an existing application that uses them.This application has a form to edit rows in detail view, so we have the navigator toolstrip with nav buttons on top, including one to add a new row.When this button is clicked, I need to update one of the bound text boxes with a value from the underlyingThe field in question is defined as nvarchar 25 It's almost always integers in this field, but one row has a string.In the dataset, I have a table adapter to go get the max value + 1 where the field is numeric, like this:
SELECT internal_num = CAST(MAX(internal_num) + 1 AS NVARCHAR(25))
FROM dbo.invoice_log
WHERE ISNUMERIC(internal_num) = 1

We are binding most of our text boxes and dropdown boxes to a BINDING NAVIGATOR (with a DATA SOURCE of a DATA TABLE).When the BN is clicked through the text boxes all change immediately.We need to use some non-bound controls as well.First one is 4 radio buttons that when clicked will change a single value in a DATA TABLE.What would be the best method to do this? Should I track when the CURRENTCHANGED event occurs on the BINDING NAVIGATOR.I'm thinking that I could trick this by BINDING the SINGLE FIELD to a HIDDEN TEXTBOX and when that textbox CHANGED event occurs mess with the radio buttons and visa-versa.

There is a connection in my program to SQL Server and there is a query which is bound to a combo box, to pull out values from the database. For some reason, I get an error message during run-time, saying that the syntax is incorrect.
Here's the query:
'The SQL Command to be executed:
projs = New SqlCommand("use " & Me.ComboBox1.Text & "''" & _
"go" & _
"select name from projects where condition = 'Y'", cnn1)
cnn1 is the name of my SQL Client connection.
